By Richard Cowan and Steve Holland WASHINGTON (Reuters) – Bowing to pressure from fellow Republicans, Donald Trump said on Tuesday he would no longer talk about a Mexican-American judge after U.S. House Speaker Paul Ryan denounced the presidential candidate’s criticism of the jurist as textbook racism. Trump said in a statement that his previous remarks about Curiel had been misconstrued. “I do not feel that one’s heritage makes them incapable of being impartial, but, based on the rulings that I have received in the Trump University civil case, I feel justified in questioning whether I am receiving a fair trial,” the presumptive Republican nominee said.
